Hi,
I am new to Angular JS, I am trying to display items in a ng-grid. In a particular column, I have to concatenate two different model fields with a "-" sign. Can somebody please help me to have a solution for this?

I tried like this,
field : 'rollnumber' + '-' + 'name';
displayName : 'NameRollNumber'

But it is not working :( .

Thanks & Regards,
Jewel Jose
